Furnace · 2 assemblies · 2 diagram sheets · 20 parts · by Andrew Strick, mobile RV technician
OEM exploded parts diagrams for the Suburban N Series RV furnace: 2 assemblies (N32CG, N32C) and 20 manufacturer part numbers. 3 parts are marked as superseded — the description gives the replacement number to order instead.
The rating plate is on the furnace chassis — slide the unit's front panel off or look just inside the exterior access door. Suburban models (SF-30F, NT-34SP …) changed burners and boards over the years, so the serial number's date range matters as much as the model.
